The disclosure provides a power allocation method for non-orthogonal multiple access (NOMA) systems and a base station thereof. The method includes the following steps: receiving a first channel estimation error parameter from first user equipment, and receiving a second channel estimation error parameter from second user equipment; configuring a first minimum rate requirement of the first user equipment and a second minimum rate requirement of the second user equipment; determining a power allocation factor according to the first channel estimation error parameter, the second channel estimation error parameter, the first minimum rate requirement, and the second minimum rate requirement; and determining first transmission power for the first user equipment and second transmission power for the second user equipment according to the power allocation factor.

A device of a receiver, a method and a machine readable medium to implement the method. The method includes: determining a residual rate to identify a decoding estimate for a first packet sent from a wireless first transmitter; determining a grouping of transmitters including the first transmitter and a wireless second transmitter scheduled to transmit a second packet; performing power optimization by determining lowest necessary transmission powers corresponding, respectively, to transmissions of the first packet from the first transmitter and of the second packet from the second transmitter, wherein the transmissions of the first and second packets are within a same time-frequency resource and together define a signal to be received at the receiver; and encoding for transmission to the first and second transmitters information on the signal based on the residual rate, the grouping and the power optimization.

Inter-protocol interference reduction for hidden nodes may be provided. A first service end point may determine that an inter-protocol interference is present on a channel. Next, an initial packet failure count value on the channel may be determined. A transmit (Tx) power for selected packets may then be increased until a subsequent packet failure count value on the channel is less than the initial packet failure count value.

Aspects of the disclosure provide methods and an electronic device for wireless communication. A method includes transmitting, by a first transceiver, control packets via a first wireless communication channel using a first radio access technology. The method includes determining, by processing circuitry, a first parameter indicating an interval between transmissions of the control packets. Further, the method includes determining, based on the first parameter, a size limit for packets to be received by a second transceiver that is configured to receive the packets via a second wireless communication channel using a second radio access technology. The method includes transmitting, by the second transceiver, information indicating the size limit over the second channel so that sizes of the packets sent by the second radio access technology are such that the packets are received by the second transceiver in a time period within the interval between the transmissions of the control packets.

According to one general aspect, an apparatus may include a pre-transmission circuit configured to encode a data signal for communication. The apparatus may include a peak-to-average-power ratio (PAPR) controlling circuit configured to set a power level for a level-adjusted data signal. In some embodiments, the PAPR circuit may be configured to set the power level by employing a multi-loop, multi-phase technique, wherein an inner loop employs multiple phases to constrain the PAPR and reduce at least one power-related error condition, and wherein an outer loop updates the power level. The apparatus may include a transmitter circuit configured to transmit the level-adjusted data signal.

A communications device including an array antenna assembly including a plurality of transmit chains, each with a transmit power amplifier, synchronously captures transmit power measurements for each power amplifier. A baseband transmitter in the communications device determines when a predetermined symbol in a protocol, e.g. a PSS SSB symbol, is to be transmitted and sends, e.g. via a SPI, a capture command to command each of the ADCs corresponding to the power amplifiers to synchronously capture a power measurement. Power measurements are captured at the boundary of the predetermined symbol, and the power measurements represent average transmit power levels corresponding to the symbol. The power measurements are communicated to the baseband transmitter which processes the data using calibration tables and taper information. Processed power measurements are compared to desired transmitter target levels and errors are determined. Based on the errors the gains of one or more TX chains are adjusted.

A signaling system includes a pre-emphasizing transmitter and an equalizing receiver coupled to one another via a high-speed signal path. The receiver measures the quality of data conveyed from the transmitter. A controller uses this information and other information to adaptively establish appropriate transmit pre-emphasis and receive equalization settings, e.g. to select the lowest power setting for which the signaling system provides some minimum communication bandwidth without exceeding a desired bit-error rate.
